Dawn (played by Jess Weixler, winner of a Special Jury Prize at Sundance for this role) leads a school chastity movement called The Promise. Dawn has little trouble holding herself to its strict standards until she meets Tobey, an upstanding lad who professes similar beliefs. Nature takes its course, however, and Tobey pushes Dawn too far. As much to her surprise as his, Tobey pays the ultimate price for his transgression. Laced with sex and gore, Teeth tells of the horror of becoming an adult. Finally, a teenage comedy you can really sink your teeth into.
